The first two categories we need to identify are modified sine wave and pure sine wave. Modified sine wave can be thought of man made power and pure sinewave can be considered as organic power. Just as organic food is generally the healthier choice for us, so is pure sinewave a healthier choice for your electronics, appliances or machines. Modified sine wave units are more cost effective at times. To read more on the differences between the two, click here.
The next set of categories to consider is offline, line-interactive and online UPS systems.
Offline UPS’s are most common in households, but not necessarily the right option to go for. Offline UPS systems are always “offline” unless you’re charging the batteries. This type of UPS should run less than 20min or it would overheat, thus these units are made to last only a short while. The attribute that is most vital to keep in mind is that this UPS will only connect and feed the load within a few seconds.
Line-interactive UPS systems is always on, purely to keep the batteries charged. Once power is lost, the connection kicks in to support the load within a matter of 10 milliseconds. Now 10 milliseconds is so quick, most equipment does not even notice that the power has dropped, however this UPS might not be ideal for a server. Most line-interactive UPS systems are fitted with Automatic Voltage Regulators(AVR) which regulates the power feeding through from Eskom which is a good system to have in place to protect your equipment, electronics, appliances or machinery.
Online UPS systems is your top-of-range UPS backup system. This system is ALWAYS online and is therefore the ultimate power stabilizer for critical loads. This UPS system will work for long periods with superior battery life.
Now there are more variables that play a part, so to ensure that you are looking at the best suitable system, reach out to us and we will help you find the system that would give you the solution that meets your needs.
